  1. Reproductive practical block Practical- I Male reproductive organs

  2. Male genital system Normal anatomy and histology

  3. .

  4. The prostate gland is shown to the right. The secretory glands, lined with simple columnar epithelium, differ somewhat in morphology as they move progressively from the urethra toward the gland periphery. • The glands near the urethra tend to enlarge with age and restrict the urethra, known as benign hypertrophy. Glands near the periphery are subject to carcinomatous change. • The glands have a characteristic folded appearance. There may also be distinct concretions that are spherical or oval concentrations of glycoprotein. concretion

  5. Gross and histopathology

  6. 1-Prostatic hyperplasia

  7. Prostatic hyperplasia

  8. Hormone which can stimulate the benign prostatic hyperplasia is Testosterone-DHT (diethylhydroxy testosterone).

  9. Hyperplasticfibromuscularstroma. • Glands lined by columnar and cuboidal cells

  10. Corpora amylacea

  11. Hyperplasia of the prostate:Section of prostate shows: • Nodular hyperplasia of glandular and fibromuscularstromal tissue. • Each nodule shows large number of glands of variable sizes lined by an inner columnar and an outer cuboidal or flattened epithelium and some are cystically dilated. • Eosinophilic hyaline corpora amylacea is present in some glands. • There is increase in fibromuscularstroma around the glands with focal chronic inflammatory cell infiltration.

  12. 2-Seminoma of the testis

  13. Seminoma Pale and lobulated testicular mass with bulging and potato like cut surface with attached and congested spermatic cord . Most important risk factor is cryptorchidism (undescended testicle ) and ectopic testis . It have a relatively good prognosis and is very radiosensitive

  14. Partial replacement of the normal testicle by a pale and yellowish homogenous and solid mass.

  15. SEMINOMA OF THE TESTIS

  16. SEMINOMA OF THE TESTIS

  17. Seminoma of the testis: Section of the testis shows: • A malignant tumour consisting of sheets of uniform malignant germ cells showing large vesicular nuclei and prominent nucleoli. • The clusters of malignant cells are separated by fibrous septae • Lymphocytes are infiltrating the septae and the tumor cells.
